Instead of reading out your Wi-Fi password letter by letter, you can put a QR code on your wall. Guests scan it, they're connected. No typing. No "is that a capital I or a lowercase l?"
Here's how Wi-Fi QR codes work and how to create one for free.
How Wi-Fi QR Codes Work
A Wi-Fi QR code encodes your network credentials in a specific text format that phones recognize automatically:
WIFI:S:YourNetworkName;T:WPA;P:YourPassword;;
Where:
-
S:— network name (SSID) -
T:— security type (WPA,WEP, ornopassfor open networks) -
P:— password
When a phone camera scans this format, it detects the WIFI: prefix and opens a connection prompt automatically — no app needed on modern Android or iOS.
Create a Wi-Fi QR Code (Free, No Login)
- Go to the QR Code Generator
- Select Wi-Fi as the content type
- Enter your network name (SSID) and password
- Choose your security type (WPA2 for most home routers)
- Customize the style if you want — colors, dot shape, corner style
- Download as PNG or SVG
The QR code is generated entirely in your browser. Your Wi-Fi password is never sent to any server.
Security Type — Which to Choose
| Security | When to use |
|---|---|
| WPA / WPA2 | Most home and office routers — choose this |
| WPA3 | Newer routers with WPA3 support |
| WEP | Older, legacy networks (rare) |
| No password | Open/guest networks |
If you're unsure, check your router's admin page or the sticker on the back of the router. Almost all modern home routers use WPA2.
Where to Put It
Printed and framed — the most common use. Print the QR code, put it in a small frame, and place it near your router or at your desk. Guests scan it on arrival.
On your phone screen — create the QR code, screenshot it, and show guests your screen. They scan directly from your display.
In a welcome document — if you run an Airbnb, short-term rental, or office, put the QR code in the welcome PDF or print it on an information card.
On a desk tent card — small folded card, QR code on one side, network name on the other. Common in coworking spaces and hotels.
Scanning a Wi-Fi QR Code
Android (8+): Open the camera app, point at the QR code. A notification appears — tap to connect.
iOS (11+): Same — open the native Camera app, point at the code. Tap the banner to join the network.
Older devices: Use a QR scanner app. Most will detect the WIFI: format and offer to connect.
No app download needed on modern phones. The camera handles it natively.
Can Someone Steal My Password From the QR Code?
Yes — anyone who scans the code gets your Wi-Fi password. Keep that in mind:
- Don't post your Wi-Fi QR code publicly online (social media, websites)
- For Airbnb or short-term rentals, use a separate guest network with its own password — not your main network
- For offices, create a guest network with limited access
Most routers support a separate guest SSID. Create a QR code for the guest network only — that way guests connect without touching your main devices.
Updating the QR Code
Wi-Fi QR codes are static — they encode the password directly. If you change your Wi-Fi password, you need to generate a new QR code.
If you change passwords regularly, consider:
- Keeping the password simple but memorable (so guests can type it if needed)
- Using a dynamic QR code that redirects to a page where you update the password centrally — though this requires more setup
For most home and small office use, a static Wi-Fi QR code works fine. Passwords rarely change.
